Competition is the key of sport. Its not just because its not fun to compete with the opponent. Their competitors will help them grow better. This sneaker is a tribute to the two legendary tennis players, Rod Lever, and Stan Smith. One shoe tongue features Rodney and one of the familiar Stann faces on the other. Because your friends should always be together like shoes. This product uses PRIMEGREEN, which is part of the high performance recycled material series.
